IMPROVED APPARATUS FOR EVAPORA''ING- SACCHARINE AND OTHERS* SOLUTIONS.

The Schedule referred to in these Letters Patent and making part of thesame.

To all persons `to whom these presents may come:

Be it known that I, ABnnn'ToLLEs, of Weathersfield, in the county ofWindsor, and State of Vermont, have invented a new and useful orImproved Apparatus for Evaporatiug Saccharine or other Solutions; and dohereby declare the 'same to' be fully described in the vfollowingspecification, and represented in the accompanying drawings, of which-Figure l is a top view, and

Figure 2, ay longitmlinal section of the apparatus.

The said apparatus is specially designed for the reduction oi'sugar-maple sap, and may be employed for evaporating or condensingvarious other liquids.

A, B, C, 1), E, F, G, H, I, J, and K, represent a gang or series ot'erapointing-chambers, formed by dividing a rectangular vessel, L, bylongitudinal and transverse partitions a b b, arranged in it in manneras represented.

The vessel L, ivhen in use, is to be arranged overa furnace or means ofheating its bottom, so that` the several compartments ot' such vesselmay be heated as occasion may require.

The 1jr-st compartment, .A, is intended to-irst ret ceive the liquid tobe evaporated.

In this compartment is a float, M, whose stem c extends up into a tube,j, provided with a screw, g, for clamping the stern to the tube, suchbeing to enable the tlout to be' adjusted in its altitude with referenceto the tube and parts connected therewith.

,The said tube extends downward from a tubular conduitvalve, h, providedwith a discharging-nose, 'L'.

The valve h extends up into a receiving-tube, t', which is closed attop, and has an iuduct, k, to conveyinto it the liquid to be dischargedinto the compartment A. The tube t is supported over the compartment Aby standards or other proper means.

The intlow of the liquid into the tube i will be estopped, when thefloat may rise so high as to carry the tubular valve h above the'opening of the induct k, into the tube i.

There are 4one or more openingsnn, through each of the transversepartitions, each of such openings lbeing provided with a swing-valve, n,arranged to play The apparatus is sell'feeding, for as the water of thesap-or saccharine liquid may be evaporated from the first compartment,the float will Vfall, and admit more, or fresh liquid, and thus acontinuous evaporation of the liquid, and a passage of it throughout theseries .ot' compartments, will be effected, the foreign matters and scumbeing mostly left in the first compartment. I

fluit I claim, as of my invention, is as follows; that is to say- Thecombination of the tube f and the clampscrew y, with the tloat M and itsstem c, the tubular discharge-valve h, and the tubular receiver lll.

Also, the combination of the tubular receiver t and the tubulardischarge-valve h., arranged substantially as set forth, and forapplication to, and to operate with the float, as specified.

Also, the combination and arrangement of the series Vot openings mandvalves n, with the series of evaporatiiig-compartments A, B, C, Soc.,and the float M, and a conduit valve-apparatus, substantially asdescribed, for supplying liquid to the first evaporatingcompartment, andregulating the lowage of such into the same. as set forth.
